Stunning video: At least five brush fires swept through Napa, Sonoma, Lake and Mendocino counties, charring nearly 30,000 acres. The inferno has destroyed homes and businesses, and has forced evacuations of thousands of people in California's wine country.

Several raging wind-whipped fires killed at least 10 people and forced massive evacuations Monday in the area around California's world-famous wine country, as Gov. Jerry Brown declared a state of emergency and officials estimated at least 1,500 homes and commercial buildings were destroyed.

California Department of Forestry and Fire Protection Director Ken Pimlott said an estimated 20,000 people have been evacuated as 14 large fires burn. The fires are burning throughout an eight-county swath of Northern California, including Napa, Sonoma and Yuba counties.

At least ten people have died as a result of the burning wildfires, officials said Monday night. The Sonoma County Sheriff's Office tweeted that seven deaths were reported in Sonoma County.

The Sonoma County Sheriff's Office said there were multiple fires reported around the county, including a "very large fire" that jumped a freeway and spread into the east side of Santa Rosa.

Multiple fires broke out Sunday night as strong winds buffeted the area. Emergency lines were inundated with callers reporting smoke in the area, prompting officials to ask that the public "only use 911 if they see actual unattended flames, or are having another emergency."

Officials in Sonoma County said all Santa Rosa City schools will be closed Monday due to the fires.

Belia Ramos, chairwoman of the Napa County Board of Supervisors, said officials did not yet have a count on how many properties were affected, either by the fire directly or by evacuations.

"We're focusing on making evacuations and trying to keep people safe. We are not prepared to start counting. Certainly with day just breaking now, we are starting to see the structures that are affected," she said shortly after sunrise.

"The gusts are very, very — they're tremendous and it's what makes this fire unpredictable. It's something that we're having to be very cautious about," she said.

Downed trees were blocking parts of one rural road and fires were burning on both sides of Highway 12 as gusts reached up to 60 mph.

“The winds picked up to 40-plus miles per hour probably, very windy, and it changed direction and it headed straight down the valley floor,” Napa resident and Ranch Markets owner Arik Housley told “FOX & Friends.”

The fires were also nearly some wineries in the famed Napa Valley. It was not immediately clear if the Francis Ford Coppola Winery was affected by the ferocious blaze, but some wineries on Silverado Trail had some damage.

Windsor Fire Chief Jack Piccinini told the Associated Press that nearly every one of Sonoma County's fire resources is being used, but it is not enough.

"Everyone in Sonoma County is spread out fighting these fires, but they don't have enough resources to handle something like this. The only thing we can do is hope the wind will come down," he said.

Community centers, the Sonoma County Fairgrounds and other local centers have been opened for evacuees.

"It was an inferno like you've never seen before," said Marian Williams, who caravanned with neighbors through flames before dawn as one of the wildfires reached the vineyards and ridges at her small Sonoma County town of Kenwood.

Williams told the AP she could feel the heat of her fire through the car as she fled.

"Trees were on fire like torches," she said.

Fires also burned in Yuba, Butte and Nevada counties — all north of the state capital. Cal Fire tweeted that as many as 8,000 homes were threatened in Nevada County, which lies on the western slope of the Sierra Nevada.

The National Weather Service issued a warning of dangerous conditions that could lead to rapidly spreading wildfires, which goes until early Tuesday. The fires created thick smoke in San Francisco, 60 miles south of the Sonoma County fire.
